@samueljohn You can't really do that. The way leiningen works is that it keeps projects and itself separate from each other. It installs its own version of Clojure (and that shouldn't necessarily be the latest because it is what leiningen runs off of and not what the user will run off of). Projects specify their own Clojure versions, and it fetches whichever version of Clojure you want.

Clojure never really gets 'installed' except for per-project.
